Two field experiments were conducted at the Experiment and Research Center, Fac. Agric., Moshtohor, Benha Univ., Qalubia Governorate, Egypt, in the summer seasons 2021 and 2022 to study the performance of seven genotypes of rice under three levels of nano-N spraying on growth, yield and its attributes. The most important results obtained from this study can be summarized as follows: The results of the study revealed that the maximum highest No. tillers plant-1 (23.26 tiller), No. spikes plant-1 (19.98 panicle), panicle length (25.41 cm), panicle weight (4.39 g), 1000-grain weight (29.11 g) and grain yield plant-1 (59.48 g) obtained by spraying with 800 ml fed-1 concentration treatment, while, spraying with zero and 400 ml fed-1 concentration treatments were decreased No. days to 50% flowering in the combined analyses. Rice genotypes were highly significant affected on all of the studied characters. G2 genotype was the earliest in No. days to 50% flowering compared with other rice genotypes, whereas, G1 genotype gave the highest values of No. tillers plant-1, No. spikes plant-1, panicle weight, 1000-grain weight and grain yield plant-1, while, G5 genotype gave the highest value of panicle length in the combined analyses. Effect of the interaction between nano-N spraying treatments and rice genotypes were showed highly significant for No. tillers plant-1, No. spikes plant-1, panicle length, panicle weight, 1000-grain weight and grain yield plant-1. Generally, spraying with 800 ml fed-1 concentration treatment under G1 genotype recorded the highest values for these traits except panicle length in combined data. It could be complemented that under the conditions of the experiment, planting G1 genotype with spraying with 800 ml fed-1 concentration is recommended. [ABSTRACT FROM AUTHOR]

Two field experiments were carried out during the winter seasons of 2020/2021 and 2021/2022 at Ras-Sudr experimental station, Desert Research Center, Western Sinai Peninsula, Egypt. The main objective of this study was to evaluate yield and yield components as well as juice quality of three sugar beet varieties (Raspoly, Halawa and Melodia) as affected by six combinations between bacterial inoculation and inducing material treatments under saline soil conditions. Results showed that the Halawa variety gave the highest values and highly significance for sucrose% and purity%. While the Melodia variety gave the highest values and highly significance for sugar yield. While, Raspoly variety gave the highest values and highly significance for root length over the combined analysis. Yield, its components, and juice quality of sugar beet, i.e., root length, root diameter, sugar yield, sucrose%, purity%, Na%, K% and proline were highly significantly as affected by the combinations between bacterial inoculation and inducing material treatments in the combined analysis. A significant impact of the interaction between sugar beet varieties and the combinations between bacterial inoculation and inducing material treatments was gained for root length, root diameter, sugar yield, sucrose% and purity% in the combined data. It could be complemented that under the conditions of the experiment, planting Raspoly or Halawa or Melodia variety with the combinations between bacterial inoculation and foliar application with proline treatment under saline soil conditions is recommended.

The experiment was carried out at the Etay El-Baroud Experiment Station, El-Beheira Governorate, Egypt during the three successive seasons of 2014-2015, 2015-2016 and 2016-2017. The present study aimed at measuring the efficiency of two methods of selection used in the flax breeding program namely; pedigree method (PM) and bulk method (BM) on one flax population droved from previous work by the other (self) in 2014. F2 seed from the previous work furnished the source material for subsequent generations of flax populations (S2465/1 x Giza 8). In 2017 season, the high yielding selected lines (20) from each methods of breeding (two methods i.e. pedigree and bulk). Comparison between two breeding methods, mean square due to breeding methods were significant for days to flowering, No. of capsules / plant, length of fruiting zone, No. of seeds / capsule, seed index, seed yield /plant, technical stem length, and oil percentage. This result indicated the difference between breading methods. The pedigree methods gave the highest value for all traits. The pedigree method proved to be more efficient than bulk method for selection based on these traits may be due to the two parent good combiner for most traits. Also, gave the earliness of days to flowering. These result in this cross where a two parent were good combiner for most trait. For days to flowering, the result indicated that the pedigree method produced more superior lines than bulk method compared the best parent with fifteen and sixteen lines respectably. The best line was No. 7 of pedigree method. As for No. of capsule/ plant, 20 and 9 lines showed significant higher than best parent for pedigree and bulk method gave the highest number of capsules/ plant . Regarding to No. of basal branches/plant, the pedigree method produced consistently none superior parent compared the best parent, with three and four lines for pedigree and bulk, respectively. For No. of seeds / capsules, only the line No. 14 of pedigree method of breeding gave the highest no. of seeds / capsule. Concerning seed index, all lines of pedigree and bulk methods surpassed the best parent. Also, the line No. 9 of pedigree method gave the behavior seed index. With regard to seed yield/plant, four and six lines surpassed significant seed. Yield compare the best parent. The best line was No. 19 of pedigree followed by No. 2 of bulk method of breeding. For total length, sixteen lines of both breeding methods surpassed significant compare the best parent. The best line was No. 1 of pedigree method (123, 67). Regarding technical stem length, fourteen and nine lines showed significant higher than the best parent for pedigree and bulk methods, respectively the best line was No. 6 (112. 67) followed by No. 5 (111 . 33) of pedigree method . For fiber percentage, none of lines showed significant compare the best parent or over mean. [ABSTRACT FROM AUTHOR]

Two field experiments were carried out during winter seasons 2020/2021 and 2021/2022 at the Research and Production Station, National Research Centre, El-Nubaria, El-Behira Governorate, Egypt. to evaluate yield and yield component for two bread wheat cultivars (Giza 171 and Misr 1) under sprinkler and dripp irrigation systems with using four concentrations of water salinity irrigation. A split-plot design with three replications was used. Wheat cultivars were randomly distributed in the main plots while, while water salinity treatments occupied the sub-plots in both seasons. Results showed that Misr 1 cultivar recorded the highest values and highly significance for plant height, No. spikelets spike-1, weight of spike(g) and grain yield fed-1.

This investigation was undertaken at the Experimental Farm of the Faculty of Agriculture, Moshtohor, Benha University during the two summer growing seasons of 2018 and 2019. To estimate combining ability under two nitrogen levels and superiority% relative two check hybrids for five quantitative characters. N levels and genotypes mean squares were significant for all studied traits. Mean squares due to genotypes x N levels were significant obtained for all studied traits. SCA was higher than GCA for all studied traits revealing that the nonadditive effects were controlled these traits. The overall study of GCA effects suggested that parents M65, M66 and M48 were significant for general combiner for grain yield, M70 and M57 for earliness and M50 and M70 for short plants and ear stature. However, the genotypes M65xM10, M17xM10, M37xM10 and M48xCLM550 showed high SCA effect for grain yield plant-1. The maximum heterosis was recorded by the cross M48xCLM550 in combined across nitrogen levels they out-yielded SC128 and SC2031 reached 18.00 and 14.00%, respectively. 100-grain weight were correlated significantly with grain yield with r values being 0.707** in the combined analysis. Factor analysis for combined across N levels divided characters of maize into three factors accounted for 78.63% of the total variability. The first factor contributed by 39.14% included ear length, ear diameter, No. rows ear-1, No. kernels row-1, 100-kernel weight and shelling%. The second factor accounted for 24.83% and is mainly loaded by days to 50% tasseling and silking. The third factor accounted for 14.66% is mainly described by plant and ear heights.

Two field experiments were conducted at Moshtohor region, Kalubia Governorate, Egypt, during 2019/20 and 2020/21 seasons, to study the effect of three sowing dates (1st November, 15th November, 1st December) and three harvesting dates (Harvesting at 150 DAS after sowing, Harvesting at 165 DAS after sowing, Harvesting at 180 DAS after sowing) on yield and yield components of two barley cultivars (Giza 2000 and Bhoth 244). The experimental design was randomized complete block design using split split-plots arrangement with three replications. Sowing dates was arranged in the main plots and barley cultivars was arranged at random in the sub plots, while harvesting dates were arranged randomly by in the sub sub-plots. The main results were as follows: Sowing at 1st or 15th of November gave the highest values of all studied traits except spike length and harvest index in first season and plant height in second season. Meanwhile, Bhoth 244 cultivar gave the highest values of spike length, No. spikelets spike-1, spike weight, No. grains spike-1, grain yield fed-1 and straw yield fed-1, whereas Giza 2000 cultivar gave the highest values of plant height, 1000-kernel weight and harvest index in the first and second seasons. Harvesting at 150 DAS increased significantly spike weight, No. grains spike-1, 1000-kernel weight and straw yield fed-1 compared with the other harvesting dates, while spike length, No. spikelets spike-1, grain yield fed-1 and harvest index increased significantly by harvesting at 180 DAS in both seasons. Plant height, spike weight, No. grains spike-1, grain yield fed-1 and straw yield fed-1 were affected by the interaction between sowing dates and barley cultivars in both seasons except plant height in the second season and No. grains spike-1 in the first season. Moreover, plant height, spike length, spike weight, No. grains spike-1, 1000-kernel weight, grain yield fed-1, straw yield fed-1 and harvest index were affected by the interaction between sowing dates and harvesting dates in both seasons except plant height, spike length, straw yield fed-1 and harvest index in the first season. While, plant height, No. spikelets spike-1, spike weight, No. grains spike-1, 1000-kernel weight, grain yield fed-1, straw yield fed-1 and harvest index were affected by the interaction between barley cultivars and harvesting dates in both seasons except plant height, No. spikelets spike-1, grain yield fed-1, straw yield fed-1 and harvest index in the first season. Regarding the interaction effect, among sowing dates, barley cultivars and harvesting dates were significant differences of plant height, spike weight, No. grains spike-1, 1000-kernel weight, grain yield fed-1, straw yield fed-1 and harvest index in both seasons except straw yield fed-1 and harvest index in the first season. It can be concluded that sowing Bhoth 244 cultivar in 1st or 15th November and harvesting at 180 DAS produced the height yield productivity under the conditions of this experiment.

The aim of this study was response to investigate the effect of three wheat varieties (Misr 2, Sakha 94 ,and Sids 12)to four planting methods (prodcasting, rows, hills on ridges and rows on beds) and two application methods (prodcasting and drilling). The results indicated that: Misr 2 variety gave the highest values of plant height, spike length, No. tillers and spikes m-2, No. spikelets spike-1, weight of grains spike-1, biological and grain yields fed-1 compared with the other varieties in the first and second seasons. planting by rows on bed method increased significantly plant height, spike length, No. otillers and spikes m-2, No. spikelets spike-1, weight of grains spike-1, 1000-grain weight, biological and grain yields fed-1 compared with the other planting methods in the first and second seasons. Plant height, spike length, No. tillers and spikes m-2, No. spikelets spike-1, weight of grains spike-1, 1000- grain weight, biological and grain yields fed-1 increased significantly by prodcasting N application method in the first and second seasons. Plant height, No. tillers and spikes m-2, No. spikelets spike-1, weight of grains spike-1, 1000-grain weight, biological and grain yields fed-1 were affected by the interaction between wheat varieties and planting methods in the first and second seasons except 1000- grain weight in the second season. Plant height, No. tillers and spikes m-2, No. spikelets spike-1, 1000- grain weight and biological yield fed-1 were affected by the interaction between varieties and nitrogen application methods in the first and second seasons except plant height and No. spikelets spike-1 in the first season. Plant height, No. tillers and spikes m-2, No. spikelets spike-1, biological and grain yields fed-1 were affected by the interaction between planting methods and nitrogen application methods in the first and second seasons except plant height, No. tillers m-2, No. spikelets spike-1 and grain yield fed-1 in the first season. Also, plant height, No. tillers and spikes m-2, weight of grains spike-1, 1000-grain weight, biological and grain yields fed-1 responded significant to the interaction of the three involved factors (varieties x planting methods x N application methods).
